Touch Sensor Device
First Claim
1. A touch sensor device, comprising:
- a substrate having an upper surface for receiving a touch operation, the substrate comprising;
a bottom conductive layer having a shielding effect for shielding external electromagnetic interference and acting as a ground;
a bottom insulation layer disposed on the bottom conductive layer and having an insulation effect;
a top conductive layer disposed on the bottom insulation layer for sensing the touch operation to generate a sensor signal;
an electrode layer disposed on the top conductive layer and including a plurality of first electrode lines, a barrier layer and a plurality of second electrode lines, wherein the first electrode lines and the second electrode lines are used for receiving the sensor signal to determine a position of the touch operation;
a top insulation layer disposed on the electrode layer and provided with an effect for preventing electrostatic discharge; and
a substrate material layer disposed on the top insulation layer for protecting the touch sensor device.

Abstract
A touch sensor device with increased transmittance, increased sensitivity and decreased thickness is disclosed. The touch sensor device includes a substrate. The substrate, from bottom to top, sequentially includes a bottom conductive layer, a bottom insulation layer, a top conductive layer, an electrode layer, a top insulation layer and a substrate material layer. The bottom conductive layer can shield external electromagnetic interference and act as a ground. The bottom insulation layer is provided with an insulation effect. The top conductive layer is used for sensing a touch operation to generate a sensor signal. The electrode layer includes a plurality of first electrode lines, a barrier layer and a plurality of second electrode lines. The top insulation layer is provided with an effect for preventing electrostatic discharge. The substrate material layer is used for protecting the touch sensor device.
